Abstract

A circuit arrangement for igniting and operating a high intensity discharge lamp including a Buck converter. The Buck converter includes a switch, a rectifier and an inductor having primary and secondary windings. The secondary winding is part of an integrator for controlling the non-conductive state of the switch. A detector responsive to the flow of current through the rectifier produces a signal supplied to the integrator output during the non-conductive state of the switch. The integrator output remains proportional to the flow of current through the inductor regardless of the state of the switch. Consequently, the time duration that the switch is in its non-conductive state can be limited while maintaining the circuit arrangement in a reliable non-self oscillatory mode of operation.
